i 105 M 7 'iia m mmafflw all whom it may conaaim Be it known that]: KARL Manx, a snbjact of the Duke of Brunswick, residing at Desaau, Germany, mypost-oiiice address being Alhreohtstrnsse 16, Dessan, Germany, have invented certain new and useful Irn rove manta in an Improved Process for yein Furs, Hairs, and the like, of which the E0 lowing is a. specification.

According to the presentjnvention a kind oil organic substances; which hitherto has not been used for the purpose .in question is unplug ed for dyeinginrs, hairs-and the like, it having been found that contain derivatives of 2.6%phenylenediamin are most adapted for dyeing these materials obtaining thus deep and fall yellow tints varying, generall n'pealziiag. from pure yollowit'o greenish ye low or reddish yallow and pwaassin a very good fastnma against :ihn nation at light and 'Weath 1.

This wiorasaidi .ltini oildei'ii atiwas is repre- SBllvtHfl llll time following gamma- 1 formula Ell in which formula R means a, anbstituent, such as hydrogen, a halogan, an. alkyl onp, an allway group and tho like. Thus :ror inatanlze by i'naans of niti'o-mota-diaminoimisol, which (an be obtained by nitrating diaoetylmotn riinminoanisol in snlfnrio acid and then splitting oft' tho acetyl group, a clear deep yellow is obtained on an unmorclantetl fair which yellow possvsses a very good fastnoss against the notion of light and waathor. Tao substances which according to the presont invention are to he apoliod in tho inilnatz' y of (Eyeing inns and the like may also he {lg oil upon the well-known mori'lants and o aapncinlly upon (Nippon, ironor nim'cianta.
